There are two real ways:

1st my favorite way, Drag the car into a heated garage overnight. Pour 1/2 gallon or 2 liters of gas line antifreeze into the tank and hope that cures the problem.

2nd Pour 1/2 gallon of gas line antifreeze into the gas tank wait an hour and pray. If the car wont start come back in 1/2 an hourr and try again. If it still wont start you have to follow proceedure #1
